摘要
A circuit for measurement of a phase noise of an oscillator may include the oscillator to generate a first signal having the same oscillation frequency as an instantaneous oscillation frequency of the oscillator. The circuit may include a first circuit that is configured to generate a second signal from the first signal. An instantaneous amplitude of the second signal may be related to the oscillation frequency of the first signal. A second circuit may be configured to integrate the second signal to generate a third signal. The third signal can be a measure of the phase noise of the oscillator. The third signal can be used to cancel some or all of the phase noise of the oscillator.
